Left 4 Dead Expansion

i thought up like a expansion pack to L4D while i was walking today...this expansion would add on to the difficulty and the fun as well well for instance...you could travel and try to protect other survivors and randomly some of the survivors could turn into a infected like suddenly you see the girl you were protecting start crying and when you go to see whats wrong she turns her head and her eyes are red and then your think...awww fuck...or like a skater punk who is wearing a hunter like hoodie but with the hoodie down you turn your back on him becuase he is fine for one moment and then the next moment your knocked down by the now hunter skater punk well it wouldnt be right away ...and like it would start with like lots of survivers and what not..like say you have a group of like 8 or 10 along with the 4 people you can be... and one would think hey zombies have infected other humans.. and like 4 to 5 of the surviors would randomly get dragged away at random moments that you have a slim possibility of saving them from there death but odds are you wont like your just walking down a allyway and unless you knew the smoker was on the roof he would just grab one of the victims away and all you would see is the victim being dragged up and over the roof top and then you would see like a few body parts flying off the roof but it would be awsome becuase like if you dont heal the other survviors some of them might get infected and turn into one of the four human like boss zombies no tanks though...that would be like in expert mode only ...and very rarely..what do you think? maybe add a new boss zombie or two? and then tehre would be the dead expansions..based on the three dead movies but yeah..I mean i played the demo and ive seen that stuff i mean your characters never get eaten...so how come they dont get infected so i thought up stuff like that...just think about it though...you randomly walk along with two girls a skater punk a big fat guy and a guy who smokes right... they have been attacked a few times you never healed them becuase you were low on health....suddenly they turn into two witches a boomer a smoker and a hunter...and they are all behind you and your team and you dont even know becuase you think they are still human until you hear the witchs cry your afriad to turn around...but you do only to get jumped by the hunter while the boomer explodes on your friends and the smoker grabs zoey...becuase you know smokers love tounge tentacle rape which is exactly what the smoker does dont tell me his tounge isnt a gaint tentacle the two witchs go and beat the shit out of the two reamining friends with the new horde that just arrived and this is all on expert the best thing is next round you watch the same five get killed by other zombies...so now you think hey your safe.... and this time you heal the surviviors who get wounded only to run into one of the former survivors now a part of the zombie horde its not impossbile it jsut ups the difficulty and excitement of the experince its only impossible if like...one of the survivers suddenly turns into a tank.... imagine a tank showing up behind you...you hear the tank roar right behind you....what do you do..run...turn around and shoot...both? now tell me would you play that expansion for L4D?"
